CHARLES H. TURNER, 0F WORCESTER, MASSACHUSETTS, ASSIGNOR TO OSGOOD BRADLEY CAR COMPANY, OF WORCESTER, MASSACHUSETTS, A CORPORATION OF MASSACHU- SETTS.

CAR-WINDOW.

Application filed December 8, 1915.

To all whom it may concern Be it known that 1, CHARLES H. TURNER, a citizen of the United States, residing at WVorcester, in the county of WVorcester and State of Massachusetts, have invented a new and useful Car-Window, of which the following is a specification.

This invention relates to a car window having upper and lower sashes and particularly adapted for use in passenger cars of the semi-convertible type. In such cars it is essential that the sashes be easily removable when the warm season begins, while at the same time the car must be capable of being completely inclosed for cold weather operation. During the mild weathen commonly occurring between seasons, it is desirable that either the upper or the lower sash be movable to provide ventilation sup plementary to that furnished by the roof ventilators.

It is the object of my invention to provide an improved construction of car window which will meet the requirements above enumerated and which will possess important advantages both in construction and in case of operation.

As described herein each car window comprises a fixed and a movable sash.

An important feature of the invention relates to the provision of sectional guideways for the movable sash, one section of each guideway being secured to the fixed sash and removable therewith, and the remaining section of each guideway being permanently secured to the window frame.

The invention further relates to certain combinations and arrangements of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of my invention anda modification thereof are shown in the drawings, in which Figure 1 is a sectional elevation of the preferred form of my invention; Figs. 2, 3 and 4? 2116 transverse sectional views taken along the lines 22, 3-3 and 44 in Fig. 1, respectively; Fig. 5 is a perspective view of the sashes and guideways removed from the window frame, the movable upper sash being raised; Fig. 6 is a view similar to Fig. 5 but showing the movable sash lowered, and the upper sections of the guideways separated from the lower sections and sashes; Fig. 7 is a detail sectional elevation Specification of Letters Patent.

movable sash in adjusted position; Fig. 8 is a detail sectional View taken along the line 88 in Fig. l and showing one of the spring catches which hold the fixed sash in position in the window frame; Fig. 9 is a sectional elevation of a modified form of my invention; Fig. 10 is a perspective view of the sashes and guideways shown in Fig. 9, the movable lower sash being raised and the lower sections of the guideways being separated from the upper sections, and sashes; Fig. 11 is a transverse sectional View taken along the line 1111 in Fig. 9 and showing the spring catch which holds the movable lower sash in adjusted position, and Fig. 12 is a detail elevation of the spring catch looking in the direction of the arrow 12 in Fig. 11.

Referring to Figs. 1 to 6, the'preferred form of my invention comprises a fixed lower sash 20, and a removable upper sash 21, the sashes fitting within a window frame comprising side'posts 22, a window sill 220, and a cap 221. The post 22 is shown in section in Figs. 2, 3 'and 4, the post be ing substantially rectangular in outline and being provided at its outer edges with laterally-extending sash-engaging flanges.

Throughout its greater portion 22* each 3) but in its lower portion 22 it is substantially thickened as shown in Fig. 4.

The upper sash 21 is slidable in U-shaped guideways preferably formed of sheet metal. Each guideway is'formed in two sections, as shown most clearly in Fig. 6, the upper section 23 being permanently secured to the side of the post 22 and the lower section 24f being secured to the fixed sash 20 in any convenient manner, as by screws 25 (Fig. 3). The meeting edges of the sections 23 and 24 are inclined to permit the easy withdrawal of the removable sections.

The upper sash 21 is freely slidable in the sectional guideways above described and may be secured in adjusted position by a spring-pressed plunger 26 (Fig. 7) or in any other convenient manner.

The fixed lower sash 20 and the sections of the guideways carried thereby are secured in position within the frame by spring catches 27 (Fig. 8) inserted in recesses in the side posts 22 .and engaging that portion of each removable guideway 24 which projects slightly above the sash 20 to which it is secured. The catches 27 are also closely adjacent to the upper edge of the sash 20 and prevent upward as well as inward displacement thereof.

The lower end of the sash 20 is positioned between the flange 22* at the lower end of each side post and the sill cap 221 which engages the inner face of the sash.

In assembling the parts the lower end of the fixed sash 20 is first placed in position and the sash is then swung about its lower edge until the removable guideways 2% are alined with the fixed guideways 23, in which position the sash is retained by the spring catches 27. When thus positioned the upper sash may be raised by sliding it in the sectional guideways 23 and 2a, which act under these conditions as single or integral guideways.

IVhen the sashes are to be removed from the car the upper sash is lowered into the position shown in Fig. 6 and the two sashes together with the removable guideways 241, are then removed as a unit from the window frame. In this condition they may be con veniently stored and there is no possibility of separating the two sashes which form a pair. Furthermore, the upper sections of the guideways, which would project above the sash 20 if formed integrally, remain permanently secured in the upper portions of the window frame.

The construction shown in Figs. 9, 10, 11 and 12 is similar in many respects to that already described with the exception that the lower sash is made movable instead of the upper sash. In these figures the movable lower sash is indicated at 40, the fixed upper sash at 11, and the sections of the,

provided in its upper edge with dowel pins 41 adapted to engage plates 15 secured in the upper end of the window frame. The lower edge of the sash 4C1 rests upon shoulders 46 which separate the narrow and wide portions of the flanges on the side posts. The removable guideways 42 are of substantially the same length as the lower sash, and extend below the fixed sash to which they are secured, as clearly shown in Fig. 10. Near their lower ends they are engaged and secured in position by "spring catches 27 as previously described. In order to secure the sash 4:0 in raised position one of the guideways 43' is provided with a series of perforations 4:7 and an additional perforation 48 is provided in the lower end of the corresponding fixed guideway 42, A springoperated latch 49 is"horizontal ly pivoted to the rear face of a plate 50 secured tothe sash 40, the latch being provided with an previously described, the lower portions 43 of the guideways remaining-fixed to the side posts.

It will thus appear that I have provided an exceedingly simple and efficient construction by which a movable sash is available for ventilation and at the same time the entire sash structure is readily removable from the window frame as a unit when it is desirable to arrange the car for warm weather operation. Furthermore, the sash structure is removable from the inside of the car and does not involve the use of'any tools whatever either when it is removed or when it is replaced.

Having thus described my invention it will be evident that other changes and media fications can be made therein by those skilled in the art without departing from the spirit and scope thereof as set forth in theclaims,

and I do not wish to be otherwise limited to the details hereindisclosed, but

hat do claim is:%

1. A car window comprising a window frame, a sash remo-vably fixed in said frame, means to secure said sash 1n said frame, a

pair of sectional guideways having a sec tion of each secured to said sash only and re -movable therewith and having cooperating sections permanently secured to the window frame and alined with the removable sections, a second sash slidable in said sectional guideways and means to secure said second sash in the sections of said guideways carried by said removable sash, whereby the removable sash supports the second sash when thus secured, and said sashes may be entirely removed from said frame and may be handled and stored as a unit.

2. A car window comprising a Window frame having side posts, a removable sash, means for securing said sash in fixed position in said frame, said means including yielding catches mounted in the side posts and preventing inward and upward movement of said'sash, guideways comprising U-shaped members secured to said removable sash and cooperating members fixed to said side posts, and a second sash supported by said first named sash and slidable in said guideways.

In testimony whereof I my 'hand.'

have hereunto set CHARLES H. TURNER.
